Connector for multiple core optical fiber

摘要

A fiber optic plug, suitable for multi-core fiber (MCF), is structured to hold satellite cores of the MCF in a precise angular positions so as to attain suitable alignment with satellite cores of a mating connector. The plug includes features to permit a ferrule holding the MCF to move longitudinally relative to the connector's housing, so that a spring may control a mating force to an abutting ferrule of a mating connector. The ferrule may be held by ferrule barrel having splines projecting away from an outer peripheral surface. The splines may slide longitudinally within notches of the connector housing or a strength member attached to the connector housing. The notches and splines have a tight tolerance, so that the satellite cores remain in a desired, set angular position.

主权项

1. A multi-core fiber connector comprising:
a ferrule; a multi-core fiber secured within said ferrule; a ferrule barrel surrounding at least a portion of said ferrule, said ferrule barrel including at least one spline extending away from an outer peripheral surface of said ferrule barrel; and a connector housing having an inner cavity receiving said ferrule barrel, said inner cavity including at least one notch receiving said at least one spline and permitting said at least one spline to move within said at least one notch in a first direction which is substantially parallel to an extension direction of said ferrule.
